The answer is most likely D

Step-by-step explanation:

All the other answers show the wrong letter for the children. For example, C. has z for 12 even thought the 12 is supposed to be for y. The same story is for A. and B. makes no sense.

So that leaves us with D(which is the only one that makes sense).

HOPE IT HELPS!!!

0. Juan has been saving for a new bike for two months. So far, he has saved
antiseptic1488 [7]

<u>Given</u>:

Juan has been saving for a new bike for two months. So far, he has saved $150 for the bike.

The money that he has saved so far is 30% of the cost of the bike.

We need to determine the total cost of the bike.

<u>Total cost of the bike:</u>

Let x denote the total cost of the bike.

The total cost of the bike is given by

30\% \ of \ x=150

The value of 30% can be written as \frac{30}{100}

Thus, we get;

\frac{30}{100} \times x=150

Multiplying both sides by \frac{100}{30}, we have;

x=150 \times \frac{100}{30}

Simplifying, we have;

x=\frac{15000}{30}

x=500

Thus, the value of x is 500.

Hence, the total cost of the bike is $500.

<h2>a) 16y</h2><h2>b) 8y</h2>

a) First, multiply the numbers 8 and 2, and we get 16.

Now, we have to multiply 16 and the algebraic notation “y”, we get the result of 16y.

<h3><u>Whenever you multiply the number(s) with algebraic notations, you need to multiply the number(s) and write the algebraic notation at the end.</u></h3>

<u></u>

b) Multiply the number 8 and the algebraic notation “y”, and we get the result 8y.

<em>Hope this helps :)</em>

I just need help with three, four, and seven. Solve the system of linear equations, and determine if the equation has one soluti
likoan [24]

3. If y=5x+9 and y=3x-2, then

5x+9=3x-2\implies2x+9=-2\implies2x=-11\implies x=-\dfrac{11}2

Then

y=5\left(-\dfrac{11}2\right)+9=-\dfrac{55}2+9=-\dfrac{37}2

(only one solution)

4. If y+2=4x, then y=4x-2. So we're told that 4x-5=4x-2 but this is impossible, because that would that for any x, we have -5 = -2. This is false, so this system has no solution.

7. "y is 6 less than 3 times x" means y=3x-6. "x is 2 more than one-third of y" means x=\dfrac13y+2. Solving the second equation for y gives y=3x-2, which would mean 3x-6=3x-2. But for the same reason as in (4), there is no solution. For any value of x, this equation gives the false conclusion that -6 = -2.
